After she tweeted a pic of her painted pregnant belly for her Twitter followers, singer Mariah Carey took the next step and is this week's Life & Style cover girl, showing off her expecting torso for the whole world to see, ending what had been a drought of coverage of her and husband Nick Cannon's upcoming non-musical collaboration, twin babies.

Of course, she's not the first mama-to-be to grace a magazine cover with a human being inside her body. Actress Demi Moore did it most famously for a August 1991 Vanity Fair shoot while she was preggers with Scout LaRue Willis, one of her daughters with ex-hubby Bruce Willis.

The last major pop-stars to show off their pregnant wares were Britney Spears and Christina Aguilera, who both posed seductively, with little on but a smile and healthy prosperous glow, in 2005, 2006, and 2008.
